Couple Frantic to Find Loved Ones in Rubble

More than 600,000 people lived in the city of Dujiangyan before the earthquake. Now there is no telling how many are dead. Much of the city lies in ruins. Hospitals, schools, apartment buildings were flattened by the force of the earthquake.

On Monday, Fu Guanyu dropped off her young son, Wang Zhilu, at his grandparents' house so she could go to work. Minutes later, the earthquake hit.

She rushed back home and saw their apartment building in ruins. She says soldiers came right away to help, but they had no equipment.

Two days later, the heavy machinery is on the way. As an excavator clears a path, Fu and her husband Wei Wang search the debris, calling for their son.
